NEW LABOULBENIALES. 691 



however, are longer more nearly straight and slender. Until an 

 opportunity occurs to examine and compare material on Ochthcrae 

 from other localities, it seems undesirable to separate either of these 

 Western Hemisphere forms from the Papuan types. 



Stigmatomyces Ochtherae nov. sp. 



Relatively short and stout, curved or sometimes straight. Re- 

 ceptacle subhyaline, the cells thick-walled, the basal broadly rounded 

 below, shorter than the subbasal, somewhat longer than broad. 

 Stalk-cell of the appendage rather deeply colored, dull brownish, 

 concolorous with the perithecium; relatively large, subtriangular, 

 short and stout, as broad as long, very prominent, overlapping the 

 upper fourth to half of the subbasal cell; its inner margin almost 

 coincident with that of the receptacle; its nearly flat or slightly 

 rounded distal surface more than twice as broad as the rather narrow 

 insertion of the appendage. Appendage relatively large and broad, 

 usually curved against the side of the perithecium, with the antheridia 

 directed outward; consisting of five to seven cells, the upper bearing 

 a single antheridium followed by a terminal one; the remainder two 

 each, the necks small, slightly curved, not prominent; the basal cell 

 deeply colored, short, cup-shaped. Stalk-cell of the perithecium 

 broader than long, paler and larger than the cells above it, which are 

 concolorous with the perithecium. Venter of the perithecium short, 

 hardly inflated, the neck not at all or very slightly distinguished, 

 considerably longer, very broad, its inner margin concave below, 

 becoming straight, its outer somewhat convex, abruptly so where it 

 joins the tip, and sometimes swollen in this region so that its diameter 

 may equal that of the venter: the tip short, its outer margin bending 

 inward almost at right angles, but otherwise hardly distinguished, 

 very short, the hyaline lips forming an abruptly papillate termination 

 close to the inner margin. Spores about 35 X 3.5 /x. Perithecia 

 100 X 31-35 /x. Appendage 70-85 X 15-20 /x- Receptacle 66-85 X 

 18-25 ju. Total length to tip of perithecium 160-180 /x. 



On the superior surface of the abdomen, near the tip, of Ochthera 

 sp., No. 1760,' Balaclava, Jamaica, W. I. 



This species is perhaps as nearly allied to S. gracilis in the character 

 of its appendage, as to any other forms, but is so peculiar that it is 

 sufficiently unmistakable. The swollen end of the perithecium gives 

 it a characteristically hunched appearance quite unlike that of any 

 known species.
